Ja 72 The Story about the Virtuous Elephant
(Sīlavanāgajātaka)
In the present Devadatta is noticed as an ingrate. The Buddha says he was like that in the past also, and tells a story of how, when he was a marvellous elephant, he had once saved a forester, who later returned and begged him over and again for his tusks, which he gave. The earth though opened up and swallowed the forester for his wickedness (full story).
1. Akataññussa posassa niccaṁ vivaradassino,
Sabbaṁ ce pathaviṁ dajjā, neva naṁ abhirādhaye ti.
The ungrateful person, always looking out for an opening, even if given the whole world, still would never be satisfied.
In this connection, ungrateful means not acknowledging the good done to oneself.
Looking out for an opening means looking around for an opportunity, an occasion.
Even if given the whole world, even if such a person had complete and Universal Sovereignty, after rolling over this great earth, and being given the essence of the earth, still would never be satisfied, though doing so, making such a destruction of the good done, some would not be able to be gladdened, or pleased, this is the meaning.
